Layered discretization is an efficient way of realizing thermal cloaks.The aim of this paper is to investigate the effect of nonlinear coordinate transformation on the thermal cloaking performance of multilayered cylindrical thermal cloak.Two indexes are defined to quantify the thermal cloaking performance.Nonlinear coordinate transformations with
Due to a battery constraint in wireless sensor networks (WSNs), prolonging their lifetime is important.Energy-efficient routing techniques for WSNs kaiser copy stands play a great role in doing so.In this paper, we articulate this problem and classify current routing protocols for WSNs into two categories according to their orientation toward eithe
The true polarization diversity (TPD) technique is combined with the spatial diversity technique in novel MIMO antenna array geometries with a large number of elements.The use of a large number of elements requires some angular reuse within the array for polarization diversity.With designs compatible gymnastics wall decals with existing base statio
Time-of-arrival transmitter localization systems, which use measurements from an array of sensors to estimate the location of a radio or acoustic emitter, are now widely used for tracking wildlife.Outlier measurements read more can severely corrupt estimated locations.This article describes a new suite of location estimation algorithms for such sys
